Recognises a threshold at odds with its rule

What it means

100 % on data known to fail, which gets the check switched off within a week; or below 100 % on a rule that is absolute — a key, a reference, an alethic rule — which turns a corrupt key into a dashboard. A threshold below 100 % with no record of who agreed it is a rule nobody agreed to.

How it is assessed

Flags the deficient case and passes the acceptable one. Deficient: `uniqueness` on `account_identifier` at `threshold: "98%"`; or a new completeness rule at 100 % over ten years of migrated data that is 92 % complete Acceptable: Keys and references at 100 %; legacy-tolerant rules at the measured rate with an agreed date to tighten, and the agreement in `comment` (`DQR-021`)
